Jackie Chan says the death of Robin Williams is like losing his ''best friend''.

Chan never got the opportunity to work with Williams, but was a huge fan of the 'Good Will Hunting' star and is saddened by the news of his passing.

He told 'Good Morning Britain': ''I didn't work with him. I met him for the first time at the Oscars a long time ago. I was standing in the green room and at that time my English was not very good.

''I see so many people in front of me and suddenly [I hear], 'Jackie Chan! [I'm a] big fan!' I didn't respond because it was Robin Williams. [I said], 'I'm a big fan, great to see you.' And then he was gone.''

Although Chan's encounter with Williams was only fleeting, he admits that the death - which is believed to be caused by suicide via asphyxiation - has affected him.

He added: ''I don't really know him, but I think today I've lost my best friend.''

This sentiment has been echoed by Steven Spielberg, who collaborated with him on 'Hook' and was also a long-time friend of the star.

He said: ''Robin was a lightning storm of comic genius and our laughter was the thunder that sustained him. He was a pal and I can't believe he's gone.''
